CUT-OFF FOR BOLTlNG-CHEST CONVEYERS.

SPECIFICATION forming part of Letters Patent No. 283,715, dated August21, 1883.

Application filed April 10,1983.

To all whom it may concern Be it known th at we, LAWRENCE B. KoHNLn andWILLIAM B, HAMILTON, both citizens of the United States, residing atLima, in the county of Allen and State of Ohio, have jointly inventedcertain new and useful Improvements in Ou't-Ofi's for Belting-ChestConveyers; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters and figuresof referen cc marked thereon, which form a part of this specification.

Our invention relates to improvements in cut-offs for boltingchestconveyors.

Our invention relates to that class of boltingchests having doubleconveyers, those in which one conveyer is placed over the other beingthe kind to which our improvements are applied.

In the present mode of dressing flour through a series of reels andtheir accompanying conveyers, in order to obtain the grade products, thestock which is discharged through the reelcloth into the first ornpperconveyor must be returned and carried through the entire system ofreels, which process consumes much time and labor and requires constantcare and attention to get the proper separation of the flour products.

The object of our invention is to obviate the necessity of this and toenable the miller to make two distinct separations of the flour productthat is discharged through the cloth into the conveyers. To accomplishthis a cutofi and spout is applied to the upper conveyerbox, for thepurpose of changing the discharge of the stock product from beingcarried into the lower conveyer-bon and delivering it directly to therolls, and at the same time allowing that part discharged into the lowerconveyer to be carried. into the purifiers, thus saving the expense,trouble, and time required in the repeated manipulation of the productby carrying it throughout the entire bolting system, as before stated.

Figure 1 is a vertical section through the conveyer-box at the tail endof the reel on line :0, Fig. 2. Fig. 2 is a top view of that portion ofthe tail end of a conveyer-box which extends 1 70 model.)

thickness, with the partition-board cbetwe-en them, and has a squarehole, 0, in it, which, when the slide is pushed in, opens into the ironspout a, seen attached to the upper and inner angle of the lowerconi-eyer-chamber, p, in the front side of the same. The slide 1) restsupon the top of spout a, which latter acts partially as a guide for thesame. The two edges of the slide 12 are beveled outward on the top, asseen at h in Fig. 3, to allow it to engage with the inner reversebeveled edges of the opening in the partition-board 0, into which theyslide closely. Strips d are fastened upon the top of the slide, neareither edge, in rear of the hole 0. These strips act as stops to arrestthe move ment of the slide, their ends striking the corner strips cl ateither side of the chamber 1) as the slide is operated.

The spout a is of iron, and is cast with a flange, 6, extending from itssides and bottom on a line with the inside of the front board of theconveyer-box, against which it is in contact, thus supporting the spouta, which is further secured by screws extending through it into thefront board. The flange, however, effectually prevents the spout fromslipping out through the front board. It is inserted from the inside ofthe latter.

The dotted lines in Figs. 1 and 2 represent the position of the slide.1) when drawn out. When the slide is closed, as seen-in Fig. 1, thetailings entering the conveyer-cliamber p are discharged through hole 0therein and through spout a, and fed directly to the rolls, as'stated.The stock from the upper conveyer is free to discharge into the chamber11' of lower conveyer through the opening made in rear of the spout whenthe slide b is drawn out.

WVe are aware that slide cut-offs with openover the other, thecombination, with the two conveyers and the two conveyer-chambers, of aslide cut-off, the partition between the two chambers having the openingfor the slide, with the downwardly and outwardly inclined sides and theinclined spout leading from the upper conveyer-chamber down through theupper front corner of the lower conveyer-chamber and out through thefront wall of the same, and having flanges projecting from the sides andbot tom of said spout inside said front wall, substantially as and forthe purpose set forth.

2. In a bolting-chest, in combination with two conveyers and twoconveyor-chambers, one over the other, an inclined iron spout leadingfrom the upper conveyer-chamber down through the'lower conveyer-chamberand outside of the same, said spout having a flange extending around thesides and bottom of its discharge end just back of the latter and insidethe wall of the lower conveyer-chamber, substantially as set forth.

stock in the upper conveyer and stops to arrest its movements, andhaving its edges beveled, as shown, and the fixed open spout ex tendingfrom said slide down through the front board of the lowerconveyer-chamber, and having its sides and bottom provided with flangesto retain it in place and to adapt it to support and guide said slidewhen operated, substanstantially as set forth.
